a) Is ethanoic acid a weak electrolyte or a strong electrolyte, give a reason for your answer. Show the dissociation of ethanoic acid in water. (5 marks) b) Given that the hydroxide ion concentration of a solution is [OH-] = 2.1 x 10-4 M, calculate the pH and state whether the solution is acidic, basic or neutral. (5 marks) c) What two processes are required for a chemical to become an electrolyte? Explain the two processes with appropriate examples. (5 marks) d) Gastric acid plays a key role in the digestion of proteins by activating digestive enzymes and often has a pH value in the range of 1.5 to 3.5. If the pH of the acid at a given time is found to be 1.25, calculate the molarity of the gastric acid juice. (5 marks) e) Isocyanic acid, also known as Hydrogen cyanate, is a weak acid and a potentially toxic atmospheric pollutant. Write down the equation for the dissociation of isocyanic acid in water. Explain the term conjugate base and state the correct conjugate base of isocyanic acid. Give a reason for your answer. (5 marks)
